Quick Answer: 250 Gallon Propane Tank Cost
A standard above-ground 250-gallon propane tank costs between $1,200 and $2,800 fully installed. Underground models range from $2,500 to $5,000 due to excavation and specialized materials. The tank alone (without installation) typically runs $600 to $1,800, depending on the manufacturer and whether it's new or refurbished.
A 250-gallon propane tank sits in the sweet spot for many US households—large enough to heat a mid-size home through a cold winter month, yet compact enough for flexible placement. If you're weighing your options between this size and a larger 500-gallon propane tank, understanding the true installed cost is essential. Prices vary widely by region, tank type, and installation complexity. This guide breaks down every cost factor so you can budget with confidence.
What Determines the Cost of a 250 Gallon Propane Tank?
Several variables influence the final price tag. The most significant factor is whether you choose an above-ground or underground (buried) tank. Beyond that, location, contractor rates, material quality, and permitting all play a role. Here's a closer look at each element.
Above-Ground vs. Underground Installation
Above-ground tanks are the most common and affordable option. Installation is straightforward: a concrete pad or compacted gravel base, gas line connection, and a pressure test. Underground tanks, on the other hand, require excavation, cathodic protection to prevent corrosion, and often a more expensive tank designed for burial. These additional steps can double the total project cost.
| Tank Type | Tank Cost (Unit Only) | Installation Cost | Total Installed Range |
|---|---|---|---|
| Above-Ground (New) | $700 – $1,500 | $500 – $1,300 | $1,200 – $2,800 |
| Above-Ground (Refurbished) | $400 – $800 | $500 – $1,300 | $900 – $2,100 |
| Underground (New) | $1,200 – $2,500 | $1,300 – $2,500 | $2,500 – $5,000 |
| Underground (w/ Excavation Challenges) | $1,500 – $2,800 | $2,000 – $3,500 | $3,500 – $6,300 |
Cost estimates reflect national averages. Regional labor rates and soil conditions can shift these ranges.
Regional Price Variations Across the US
Where you live significantly affects what you'll pay. Here's how costs break down across major US regions for a new above-ground 250-gallon tank installation:
| Region | Average Installed Cost | Key Cost Drivers |
|---|---|---|
| Northeast (NY, MA, PA) | $1,800 – $2,800 | Higher labor rates, strict permitting, older homes |
| Southeast (FL, GA, NC) | $1,200 – $2,200 | Moderate labor, fewer frost-depth requirements |
| Midwest (OH, IN, IL) | $1,300 – $2,400 | Competitive contractor market, seasonal demand |
| Southwest (TX, AZ, OK) | $1,200 – $2,100 | Lower labor costs, minimal frost concerns |
| West Coast (CA, OR, WA) | $1,800 – $2,800 | Elevated labor, seismic strapping requirements |
New vs. Refurbished: Which Should You Choose?
A new 250-gallon propane tank comes with a full manufacturer warranty—typically 10 to 15 years—and zero concerns about prior wear. Refurbished tanks cost 40% to 50% less upfront but may carry a shorter warranty and require closer inspection. For underground installations, we strongly recommend purchasing new; the cost of excavating a failing buried tank far outweighs the savings on a refurbished unit.
What's Included in a Standard Installation?
When you get a quote from a licensed installer, the following components are typically bundled into the total price:
- Concrete pad or gravel base – provides a stable, level foundation
- Gas line connection – copper or polyethylene line from tank to home
- Pressure test – ensures the system holds pressure safely
- Regulator installation – controls gas flow to appliances
- Permit fees – varies by municipality ($50–$300)
- Basic backfill and grading – for underground tanks
Some contractors exclude the concrete pad from their base quote, so always confirm what's covered before signing. For broader home service costs, we recommend comparing at least three written estimates.
Additional Costs to Budget For
Beyond the tank and core installation, several optional or situational expenses can arise:
- Protective tank cover or dome: $50–$150 for above-ground units, shielding the regulator and valves from weather
- Seismic strapping: $100–$300, required in earthquake-prone zones like California
- Tank painting or coating: $200–$500, extends tank life in coastal or humid climates
- Propane fill: A full 250-gallon tank holds roughly 200 gallons of propane (80% capacity) at a cost of $500–$800, depending on seasonal fuel prices
- Relocation of existing utilities: $300–$1,000+ if gas, electric, or water lines need rerouting
Common Mistakes to Avoid
Even savvy homeowners make errors when budgeting for a propane tank. Here are the most frequent pitfalls:
- Skipping the site survey. A professional should evaluate soil stability, access for delivery trucks, and setback distances before you commit to a location.
- Ignoring local code requirements. Setback rules (distance from property lines, structures, and ignition sources) vary by county. Non-compliance can mean expensive corrections later.
- Choosing the wrong tank size. A 250-gallon tank suits most 1,500–2,500 sq ft homes for seasonal heating and cooking. If you're also running a pool heater, generator, or workshop, you may need a larger capacity.
- Not comparing fuel contracts. Some companies lock you into above-market propane rates in exchange for a "free" tank. Read the fine print.
- Overlooking tank cover costs. A protective cover or dome extends the life of your regulator and fittings—budget $50–$150 for this small but worthwhile add-on.
For other major home system installations, such as central air conditioning, similar diligence around permits and contractor vetting applies.
How Long Does a 250 Gallon Propane Tank Last?
A well-maintained above-ground propane tank typically lasts 20 to 30 years. Underground tanks have a shorter lifespan—15 to 25 years—due to soil corrosion, even with cathodic protection. Annual inspections and prompt repainting of surface rust can add years to your tank's service life. Most manufacturers include anode bag replacement schedules in their warranty documentation.
Leasing vs. Buying: A Quick Comparison
Leasing removes the upfront equipment cost but ties you to a specific propane supplier. Buying gives you freedom to shop for the best fuel prices. Over a 10-year period, purchasing usually saves $800–$1,500 compared to leasing, assuming average propane consumption and price fluctuations. However, leasing includes free repairs and maintenance, which can offset the difference if your tank requires service.

Frequently Asked Questions
How much does a 250 gallon propane tank cost on average?
A new above-ground 250-gallon propane tank costs between $1,200 and $2,800 fully installed, including the tank, pad, gas line connection, and pressure testing. Refurbished tanks can bring the low end down to around $900.
How much does a 250 gallon underground propane tank cost?
Underground installation for a 250-gallon tank ranges from $2,500 to $5,000. Excavation, cathodic protection, backfilling, and higher-grade tank materials all contribute to the increased cost compared to above-ground models.
How much does a new 250 gallon propane tank cost vs. a used one?
A new 250-gallon tank alone (without installation) costs $700–$1,500. A refurbished or used tank runs $400–$800. The price difference narrows when you factor in installation labor, which remains roughly the same for both.
What factors affect the cost of installing a 250 gallon propane tank?
Key factors include above-ground vs. underground placement, local labor rates, permit fees, soil conditions, distance from the tank to the home, and whether additional work like concrete pad pouring or seismic strapping is required.
How long does a 250 gallon propane tank last?
Above-ground tanks last 20–30 years with proper maintenance. Underground tanks typically last 15–25 years. Regular inspections, rust prevention, and anode bag replacement (for buried tanks) maximize longevity.
Does a 250 gallon propane tank need a protective cover?
While not strictly required, a protective cover or dome for an above-ground tank costs $50–$150 and shields the regulator, valves, and gauge from rain, snow, and UV damage—extending the life of critical components.
